Qualifying Pennsylvanians can finally buy legal medicinal cannabis products, and they’re selling out fast, even with price tags more than double of the state’s black market.

Pennsylvania’s long-awaited medical cannabis program is finally up and running, offering Keystone State residents suffering from 17 severe conditions the ability to legally purchase, possess, and consume a number of THC and CBD concentrates, topicals and tinctures. But as patients traveled hundreds of miles and lined up to access the newly legal medicine, licensed sellers, buyers, and state officials reported high prices and limited options, with a number of specific products selling out only hours after sales began on February 15th.

According to the Philadelphia Inquirer, over 1,700 patients visited Pennsylvania’s six active dispensaries from February 16th to 23rd, with each customer spending an average of $200 per visit.

“We’ve been working to get medicines to patients as quickly as we can,” Pennsylvania Department of Health spokeswoman April Hutcheson told the Inquirer. “To see that come to fruition is a big win for the moms with sick children and all the patients who needed this medication.”

Thanks to a focus on life-threatening illnesses, Pennsylvania’s medical program is only open to a small fraction of the state’s population and does not offer smokable marijuana flower. While qualified patients can now purchase full-strength THC oils, waxes and tinctures, a limited number of suppliers and initial offerings has resulted sticker shock and low stocks of products for patients.

In addition to steep prices, Chris Visco, co-owner of Sellersville dispensary TerraVida said that one batch of highly potent Rick Simpson Oil was mislabeled, with one container of the product labeled to contain 10 doses, instead of the 100 dosages it actually holds. Visco told the Inquirer that dispensary officials immediately alerted Cresco Yeltrah — the state’s only up-and-running cannabis producer — who immediately sent out corrected labels.

And because Cresco Yeltrah is the only producer currently providing cannabis to the legal market at present, the company is already having a hard time keeping up with Pennsylvania’s demand, leading some products, including some CBD capsules and strains of shatter, to sell out at multiple dispensaries across the state.
